Politics of Gabon takes place in a framework of a republic whereby the President of Gabon is head of state and in effect, also the head of government, since he appoints the prime minister and his cabinet. The government is divided into three branches: the Executive (headed by the prime minister (although previously grabbed by the president), the legislative that is formed by the two chambers of parliament. The judicial branch, like other two branches, is technically independent and equal to other three branches, although in practice, since its judges are appointed by the president, it is beholden to the same president. Since independence the party system is dominated by the conservative Gabonese Democratic Party.
In March 1991 a new constitution was adopted. Among its provisions are a Western-style bill of rights, the creation of the National Council of Democracy that also oversees the guarantee of those rights and a governmental advisory board which deals with economic and social issues. Multi-party legislative elections were held in 1990-91 even though opposition parties had not been declared formally legal.
Under the 1961 constitution (revised in 1975 and rewritten in 1991), Gabon became a republic with a presidential form of government. The National Assembly of Gabon has 120 deputies elected for a five-year term. The president is elected by universal suffrage for a seven-year term. The president appoints the prime minister, the cabinet, and judges of the independent Supreme Court. The government in 1990 made major changes in the political system. A transitional constitution was drafted in May as an outgrowth of a national political conference in March–April and later revised by a constitutional committee. Among its provisions were a Western-style bill of rights; creation of a National Council of Democracy, which oversees the guarantee of those rights; a governmental advisory board on economic and social issues; and an independent judiciary. After approval by the National Assembly, the PDG Central Committee, and the president, the Assembly unanimously adopted the constitution in March 1991. Multi-party legislative elections were held in 1990-91 although opposition parties had not been declared formally legal.
